摘要
研究了车载GPS/DR/DM组合导航系统.通过分析GPS(GlobalPositioningSystem)和DR(Dead-Reckoning)各自导航、定位的原理及特点,以及DM(DigitalMap)的特点,设计了一种新型的低成本车辆兵器GPS/DR/DM组合导航系统,并且用自适应的扩展卡尔曼滤波对组合系统进行了仿真实验,证明了本系统的可行性.车辆GPS/DR/DM组合导航系统无论从精度还是可靠性来说较常规的导航系统都有明显的改善和提高,GPS/DR/DM组合导航系统是一种较为理想的车辆导航系统.
To design a GPS/DR/DM integrated vehicle navigation system, after analyzing individual principles and characters of navigation and positioning system of GPS and DR, a kind of new cheaper GPS/DR/DM vehicle integrated navigation system has been designed and simulated with the integrated system by using the adaptive and extended Kalman filter, It is proved practical. The GPS/DR/DM integrated vehicle navigation system has been progressed and advanced more than the common navigation system both in reliability and precision. The GPS/DR/DM integrated vehicle navigation system is a more suitable vehicle navigation system.
